MR-S3 3 axis drive

[zsbojtos]

Hi everybody,

We have a Mitsubishi MR-S3-80AA-E-01 drive (3 axis). One of them is went wrong. I found the problem on it, the current measure part (DK-431, BKO-NC2046).

Does anybody know where can I get it (new or used) ?

Thanks Zsolt

i have the same drive with a different problem,could you read a part number off a component on your board for me,my part blew and the number is no longer readable,at the oppisite end of the board from your part is a black heat sink with voltage regs on it looking directly at them it would be the second reg in from the left,would help me out to know the numbers,maybe in my search for my parts i could find yours

thanks,steve

Could you take a picture from your bad part?
Or Could you tell me the position number of part?

i think its IC1 on the board,its a small voltage regulator bolted to the black heat sink,theres new boards and drives for sale on ebay,but very expensive

I found same company on the web. They want to buy!!! not sell.

The 5v voltage regulator, fastened to the 1 inch tall heat sink is probably a 7805. 7805ct is rated at 1.5 amps. These are very cheap on ebay. I have changed to one of these which did not fix the problem but also did not give a new alarm.
